Former President Joe Biden undergoing radiation therapy for prostate cancer, spokesperson says
Former President Joe Biden is undergoing radiation and hormone treatment as part of a treatment plan for prostate cancer, a spokesperson told CBS News.
A person close to Biden told CBS News that the former president is doing well and responding to treatment. Another person familiar with Biden’s treatment said it started “a few weeks ago and is continuing.” He is being treated in Philadelphia.
Biden was diagnosed with an “aggressive form” of prostate cancer in May 2025. According to a press release from his office at the time, the former president had been diagnosed with “prostate cancer, characterized by a Gleason score of 9 (grade group 5) with bone metastases” after the discovery of a small nodule in the prostate.
Gleason scores are a scoring system, and the lower the score, the more similar the cancer cells are to normal cells. A score of 9 is the second highest, CBS News previously reportedand places Biden in the most aggressive risk category.
Prostate cancer is the second most common cancer among men, according to the Cleveland Clinic. Age is the most common risk factor. This disease is subject to many forms of treatment, including radiotherapy, chemotherapy, surgery and hormonal treatment.
The former president was also treated for skin cancer two years ago. At that time he was in office. The White House physician said Biden had a small skin lesion with cancerous tissue removed from his chest during his annual physical. Further testing confirmed that this was the case basal cell carcinomathe most common form of skin cancer.
Biden underwent surgery for skin cancer in September 2025. This procedure was a Mohs operation, which involves cutting thin layers of skin until only cancer-free tissue remains in the affected area.
NBC News was the first to report it.
